SPECIFICATION forming part of Letters Patent No. 287,165, dated October23, 1883,

, Application filed April 10, 1883. (N0 model.) i

To all whom it may concern Be it known that I, FREDRIOK RENTsCHLER, ofthe city and county of San Francisco, State of California, have inventedan Improved Bed- Lounge; and I hereby declare the following to be afull, clear, and exact description thereof.

My invention relates to the class of bedlounges, and to certain new anduseful improvements therein.

The object of my invention is to gain an extension in the length of thebed when the back is let down as a bed, and yet not have too high aback'as a lounge.

Referring to the accompanying drawings, Figure 1, Sheet 1, is an endelevation, showing the back raised as a lounge, and the manner in whichsaid back is fitted to the seat, and the hinge and latch which hold themtogether. Fig. 2, Sheet 1, is an elevation of same, showing the backlowered for a bed. Fig. 3, Sheet 1, is a plan showing the treadle forreleasing the latch. Fig. 4, Sheet 2, is a a vertical section throughthe open seat of the bed, showing the construction of the frames andsprings at the meeting edges of the upper and lower portions. Fig. 5,Sheet 2, is a plan of same.

A is the seat portion, and B the back. The end pieces of the frame ofthe seat are cut out to form a shoulder, a, and the back is fitted downinto this shoulder, as shown in Fig. 1. Bolted by one end to the endpiece of the back is a curved iron or hinge, O, to the lower end ofwhich is pivoted the latch D, having a slot, (1, with a small turn orsocket, d, in its end.

Eis a staple driven into the frame of the seat, and passing through theslotted latch,

which of its own weight falls down, so that it latches itself by itssocket (1.

G is a plate forming atrack or guide. This is bolted to the frame of theseat, and it has an upper portion formed into a socket, g, through whichthe curved iron or hinge 0 passes. When these parts are in position, asshown in Fig. 1, the lower end of the curved iron is under the point ofplate G, and for this reason theback cannot be raised vertically. Now,if the latch D be raised, so as to free its socket d from the staple E,the baclgngybekwered. The lower end of the curved hinge CtraVels uponthe edge of the guide-plate G, at first forcing back the slotted latch Dupon the staple, and then turning itdownward until all the parts reachthe position shown in Fig. 2. The guide-socket 9 holds the curved hingeto-its place and properly directs it. The object of this arrange ment ofseat and back and this construction 'of hinge will be seen from thefollowing eX- planation: The point marked 1 in Fig. 1 is down in thecut-out portion of the seat, and the point marked 2 is on a level withthe top of the lower frame of the seat. Now, when lowered, as in Fig. 2,the point 1 moves up to the position of point 2, while point 2 movesoutwardly, and therefore the length of the bed is increased by thedistance of line 1 2. I obtain this increase in length without havingthe back too high whenin'position, because it fits down into theshoulder a of the seat. The curved hinges enable the back to make itsmovement. shoulders 1*, which, when the back is lowered, bear againstthe rear of shoulder a, as shown in Fig. 2, and steady the back.

In Fig. 3 I show the means for releasing the latches. II is abar havingends h, which ex- 1 tend through slots h in the lower edge of the frameof the seat. These ends lie just under the ends of the latches D.Connected with the bar H is a frame, I, which is pivoted at j to across-piece, J, between the legs or sides of the seat-frame. This formsa treadle. By placing the foot upon the treadle the bar H is thrown up,so that its ends hlift the latches D,

to throw their sockets or notches (1 out of en-' gagement with thestaples E, when the back may be lowered.

In all lounges of this character where two parts are hinged together, asthe lower and upper or cushion portion of the seat, the framework ofboth portions extends along their adiacent edges throughout their entirelength. This necessitates the separation of the spring at this edge,andleaves a hard place in the cen ter of the bed. This is uncomfortable andtherefore undesirable. In Figs. 4c and 5 I show my improvement in thisrespect, The under portion of seat A has a slat, m, at its lower edge,as seen in Fig. 4, but has none at its upper edge, while the upper orcushion portion, A, has no Upon the rear of the back I form cross-slatsat all. Both frames are cut out along their edges,leaving onlysuificient of the frame on each side to form bearings 0 for thehinges,as shown in Fig. 5. The edge springs S in the under portion of theseatare set on their under slots, but have no covering except theupholstering. The edge springs S in the upper portion are set entirelyin the upholstering. These adjacent springs in the two portions arehinged directly together in any suitable manner, as by wire at theirtops, they being placed close together, which construction is possibleby having no hard frame at the edge. When the cushion portion A isturned up, its edge springs turn over on the edge-springs of theseat'portion and rest 011 top of them, having only intervening somelittle stuffing, which forms the surface of the bed when opened out; butthere are no hard frames at this hinged edge, and therefore the entiresurface of the bed, when opened out, is soft, and a perfect spring frontis also formed when the device is used as a sofa or lounge.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, 'is- 1. In a bed-lounge, the seat portion A,having the rear of its frame cut away to form a recess and a shoulder,a, in combination with the back portion, B, cut away on its rear lowerside to form recesses adapted to fit in the recessedframe A,andshoulders 1', bearing against the rear portion of shoulder a when theback is turned down, and a hinge-connection be tween said seat and back,substantially as herein shown and described.

2. In a bed-lounge, the seat portion A, having the rear of its frame cutor framed out to form a shoulder, a, in combination with the backportion, B, fitting down into said shoulder,whether raised or lowered,and the means for hinging the two together, consisting of the curvediron 0, socket g, latches D,having slots d and notches d, and thestaples E, substantially as herein described.

3'. In a bed-lounge, the seat and back, in combination with the curvedirons G, slotted latches D, staples E, and guide plate or track G,having socket 9, through which the curved irons pass, substantially asand for thepurpose herein described.

4. Inabed-lounge, the seat andback, in combination with the curved ironsG g, slotted latches D, having a socket or notch, d, the staples E,engaging with said notch, and means for disengaging them to release thelatches, substantially as and for the purpose herein described.

5. In abed-lounge, the seat and back, in combination with the curvedirons 0 g, slotted latches D, having a socket or notch,d', thestaples E,and the means for disengaging said latches from the staples, consistingof the pivoted treadle-frame I, and bar H, having pro jecting ends h,working under the latches D, substantially as herein described.

In witness whereof I hereunto set'myhand.
